It's the Platinum Jubilee. Platinum is a heavy metal and while some heavy metals are needed by the human body, others are toxic. Platinum is neither – just kind of boring and non-reactive.Margaret Wyeth, Victoria, British Columbia, Canada

• Who care's about the jubilee for her 70th? All loyal subjects await when she reaches 72 years and 111 days on throne. That's one more day than the reign of Louis XIV.

It will be more satisfying than winning a FIFA cup against the French!NH Clarke, Kingston, Ontario, Canada
